Welcome to an underwater world!

Coral reefs are among the most beautiful places in the world. If we visit a coral reef,
using a face mask, a look box or looking through a glass-bottom boat, we see a strange and
wonderful world. Corals of different shapes and sizes and colors grow here. Some look
like rocks; others have bushy branches that stand firm in the currents.

Large coral reefs form masses of stony rock. They create food and shelter for other
living creatures. Many kinds of small plants and animals live on, around, and within these
coral boulders. Hundreds of colorful fish swim among the corals and hide in their
shadows. Together, all these forms of life make up the coral reef.
